t I .nppucatioirmea apri; 12, 191e. serial 1am-fammi#- Be it known. that I, FRANK p l LAND, acitizen of theUnited States,l residing at Cincinnati, in the county ofl-amiltonl 5- and vState of Ohio, have invented certain -useful` Improvements in Folding Boxes, 'of which the following is a specification, reference vbeing had therein to the .accompanying drawing. t .j-

m This invention relates to improvements in folding boxes, one object of the invention being the provision-.of a tray box in which the ends and side walls are permanently connected together in such a .manneras to permit of saidwalls when collapsed to lie in the same plane and which will permit the easy extension of said walls and the'flocliingy thereof in extended position without the insertion'o'f the provision of a box of this type in which ,the end walls, carry ja reinforcing .Hap which in turn coperates with extensions i carried by. the side walls so that such members may be stapled orpermanently fastened to the endv walls and at the same. time permit of the collapsing'of-the tray so that the end walls will be moved outwardly and the side walls moved inwardly and at the same time not interfere with the connecting members of the walls,

A stilll -further object of .this invention is.

the provision of. a] box of this character which is simple, durable and inexpensive in construction' and 'which `is thoroughly eincient and practical in use;

In the accompanyingdrawings: Figurei is a plan view of a blank of one end of the tray. `Fig. 2 is a similar view showing the.

ends attached and in collapsed position. Fig.

tended. Fig. 4 is a section through the edge Hap of the end wall and adjacent parts.

f Figs. 5 and 6 are views in blank ofmodie'd forms. .t l f Referring tothe drawings, the numeral 10 designates the bottom o f the box andll the two side walls thereof, the end wall 12 being connectedpermanently to 'the bottom and side -walls throughwthe instrumentality `of the two triangular connected inernbers 13 and 14 which are provided with the diagonal fold 15 and slitlS. Carried bythe member '14 is an'extension 17 whose base is a fold line .11e which with the fold 15 and the slit 16 forms a diagonal at the corner of the box. n

A still further object of th1s invention is When the side Awalls'andend walls are.

connected, the`exten`sionsl7 are folded'lto i i `Sp'c-:ciication of Letters Patent.-

be co-extensivewithfthe inner wall of the'v l end, 'while the flap 19 uponthe upper edge of the end wall is folded inwardlyand is secured to theend wall 'and the respectiveex-- ytensions 17 .by means of two staples 20. ln

this manner the side walls of the box may be 5 -j extended inwardly vwhen collapsed, while the end walls are extended outwardly, the iijap 19. andthe extensions 17 remaining in sucht'Ijf',

stapled' position at all times.

Carried by the Hap 19 is an extension ter-y fro' minal flap 21 having the curved edges 22,

the ap 19 being of suicient length'toextend within the box when the ytray is extend- -ed and having its short edges 19 engage the side walls while the-extension flap or locking member 2l is folded under and upwardly.' to engage the end wall between. suchend wall y.

and the extension/17. Thus the iiap 21 operf ates and is locked tohold the Hap 19fflat' andk vthe ends braced against collapsing.

` Fig. 5, the corner iiap `(ani-,to4 `provide the' flap 23, .which forni-s ajpartof the flap 17, the same being folded to yassume `the position shown at the left. v f l 13" carried the 1 VIn Fig. 6, the. corner flap extensions 1'7", while an additional-securingA flap 24 is carried thereby, staples 25 .being t' .provided to connect the flap 24 to the end o'f the box, the end of the box being formed similar to the other construction heretofore set forth. This construction providesl an ex-V ceedingly rigidbox for a deep box in that -instead o' being secured by staples as other forms, the additional staples 25 and se curing flaps 24fare provided.. A-

What I claim as new szdevices for connecting the end iaps, and extensions to the end walls, and a locking flap carried by each end flap interpositioned between the extension and the end ',wall ad- `jacent thereto whereby lthe box is locked 'inr its extendedfposition.4 t

'- 2. A folding boxcoin'prising bottom, side, and end walls, foldable corner pieces connect-1f ing the side and end walls, extensions `carried.

.-95 1. A folding boxcomprising ablank having bottom, yside andend'walls, adiagonally j folded connection between the side and end walls, an extensionpn each 'connection and meetingv the diagonal fold thereof, anend'. flap of the same length as each end wall and. carried thereby and adapted to be folded'in- .v wardly and upon said extensions, fastening by the corne;` pieces and protruding from the folds thereof, said extensions being adapted s to lbe in the same plane, foldable end aps on the end walls and engageable with the extensions, means for connecting the end flaps neoting the side and end walls, extensions carried by the Corner. pieces and protruding from the folds thereof, said extensions being adapted to be in the same plaine, foldable end flaps on the en d walls and engageable with the extensions, means for Connecting the 'end flaps and extensions to the end walls, and

means on the end flaps `for interpo'sition between the extensions and the end walls, said extensions being foldable to be co-extensive 20 with the inner surfaces of the end walls.

I n testimony whereof I ailix my signature.
